This module allows you to plot and output Radial or Radar charts using the GD library. The module is based on GD::Graph in how it can be used where possible.

A radial chart has multiple axis spread out from the centre, like spokes on a wheel. Each axis represents a particular measurement. Values are plotted by marking the value for what is being measured on each axis and optionally joining these points. The result can look like a spiderweb or a radar depending on how you plot the values.

Style can be Notch, Circle, Polygon or Fill. The default style is Notch. Where style is set to Fill, the data sets are also filled, as opposed to lines drawn for all other styles

Colours can be any of the following: white, black, red, blue, purple, green, grey, light_grey, dark_grey, cream, yellow, orange. The first colour is used for the background colour, the second is used for the scale markings, while the remaining colours represent the different data sets. If there are less colours than data sets, colours will be taken from the unused set of defined colours.

Both legend and title can be undefined. If this is the case then the relavent entry will not appear on the graph. This is useful if you plan to use other forms of labelling along with the graph, and only require the image.
